EARL CLEMENS, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO HENRY E. LAZARUS, OF CHICAGO, ILLINOIS.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 785,062, dated March 14, 1905.

T0 (LZZ whom it may concern.-

Be it known that I, EARL CLnMuNs, a citizen of the United States. and aresident of Chicago, in the "county of Cook and State of Illinois, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is afull and complete specification, sufficient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to stoppers for bottles of the kind known as spring stoppers, wherein a wire spring is attached to a base, and a rubber disk is secured in the base, such stopper constructed so that the same may be forced into the neck -of a bottle, the bottle filled, and the stopper then drawn upward into the neck of the bottle until the bottle is closed by the rubber disk. Stoppers of this description are principally used in soda-water bottles, and at times the rubber disk adheres to the glass bottle firmly, tending to cause bending or breaking of the spring whenopening the same.

The object of this invention is to obtain a stopper for bottles which may be forced from the neck of the bottle into the body of such bottle without fear of breaking or injuring the same for the purpose of permitting the stopper and bottle to be simultaneously washed; to obtain astopper of the kind named which will have duplicates prings, so that if one thereof is bent or broken such bending or breaking will not interfere with the operation of the stopper.

A further object of the invention is to obtain a stopper of the kind named wherein the button of the stopper will not be liable to be pulled off the wire spring thereof when an attempt is made to force the stopper down into the bottle to permit the contents thereof to flow therefrom.

In the drawings referred to as illustrating this invention, Figure 1 is avertical sectional view of a stopper embodying this invention. Fig. 2 is a top plan view of a stopper embodying this invention. Fig. 3 is a vertical sectional view of the upper end of the neck of a Application filed September 1'7, 1904. Serial No. 224,846.

bottle and of astopper embodying this invention therein.

A reference-letter applied to designate a given part is used to indicate such part throughout the several figures of the drawings wherever the same appears.

A is a spring substantially C-shaped, such spring having an opening on one side, as at a, and having the reverse bend 0; on the opposite side thereof. The free ends a a are thus obtained.

B is a metal button attached to the lower end of spring A, as by flowing the metal forming such button around the lower end of the spring while such metal is in a molten state. The button B consists of the disk 6, the disk 6 of larger diameter than, is the disk 6, and the post 6 connecting the buttons together.

C is a rubber disk on post 6 between the disks 6 6'.

D is the neck of the bottle.

As will be observed by reference to the drawings, the wire spring A in this stopper is bent so as to obtain two spring ends a and a and either of such ends may be bent or broken so as to fail to perform its functions, whereupon the other of such springs will maintain the stopper in the neck of the bottle, so that the stopper will close the neck of the bottle. In practice I find there is but little danger of breaking the spring end 0, and that the spring end a at times will be broken in opening the bottle, because of the rubber button becoming old and wedged in the neck of the bottle or sticking thereto.

It will be found that this stopper can be forced into the bottle and that the bottle .can then be washed on a machine and that at such times when the inside of the bottle is washed the stopper will also be so washed that there will be no dirt adhering to it to be washed off therefrom and into the bottle by the pressure of the liquid filling the bottle. After the stopper is washed while in the bottle and at the same time the bottle is washed it can be pulled back in place in the neck of the bottle and it is ready for use.

I find in the use of this stopper that when a bottle is being filled in case the hook strikes the spring-wire thereof the same is not bent or broken out of shape and the stopper can be pulled back into place and used. I also find that by having the spring end a to protect the spring end a as the stopper is forced into the neck of the bottle there is no liability of the spring end a slipping over onto the outside of the neck of the bottle, as would be the case if the spring end a were not present, and that therefore the stopper is more easily inserted in the neck of a bottle than if the spring end a were the only spring end of the stopper.

The button 5 is made of about the size of the neck of the bottle, while the upper button I) is made smaller, so that as the stopper is forced into the neck of the bottle the rubber disk C may be forced in without tearing such disk from the post 5 When made in this way, the stopper cannot be drawn or forced upward through the neck of the bottle and the bottle will be corked by the rubber disk G,-

and when the button B is attached to the spring A, as described and as illustrated in the drawings'that is, by placing the lower bend of the spring A in the body of the button Bsuch button will not in practice be drawn off the spring. Further, when the C- shaped spring A is constructed as shown and described there are two contact-points on the back thereof with the bottle-neck D when the bottle isclosed with the stopper, as is well illustrated in Fig. 3. Hence either of the ends a cfwill be sufficient to hold the spring in place closing the bottle.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is

A bottle-stopper comprising a C-shaped wire spring provided with an inward bend on the closed side thereof, and with the ends of the wire on the open side thereof bent inwardly, metal disks attached to one end of the C-shaped spring, and a rubber disk between such metal disks, in combination with a bottle-neck the opening whereof is convex longitudinally to obtain a plurality of contactpoints on the closed side of such spring when the bottle is closed by such stopper; substantially as described.

EARL CLEMENS.
